This repository shares example code and example prompts for accomplishing common tasks with the OpenAI API. To try these examples yourself, you’ll need an OpenAI account. Create a free account to get started. Most code examples are written in Python, though the concepts can be applied in any language. In the same way that a cookbook's recipes don't span all possible meals or techniques, these examples don't span all possible use cases or methods. Use them as starting points upon which to elaborate, discover, and invent.
Renderer for the harmony response format to be used with gpt-oss.
The gpt-oss models were trained on the harmony response format for defining conversation structures, generating reasoning output and structuring function calls. If you are not using gpt-oss directly but through an API or a provider like HuggingFace, Ollama, or vLLM, you will not have to be concerned about this as your inference solution will handle the formatting. If you are building your own inference solution, this guide will walk you through the prompt format. The format is designed to mimic the OpenAI Responses API, so if you have used that API before, this format should hopefully feel familiar to you. gpt-oss should not be used without using the harmony format as it will not work correctly.
The OpenAI .NET library provides convenient access to the OpenAI REST API from .NET applications.
